Mason&#39;s hand tool

ABSTRACT

A mason&#39;s hand tool includes a blade, a handle, and a head cap. The blade is fastened with one end of the handle. The handle has a head end opposite to the one end of the handle. The head cap is fastened with the hand end. The handle and the head cap are made integrally of a plastic material by injection molding. The head cap has a plurality of protruding which are anchored in the head end of the handle.

FIELD OF THE INVENTION

The present invention relates generally to a hand tool, and moreparticularly to a mason's hand tool.

BACKGROUND OF THE INVENTION

As shown in FIGS. 1 and 2, a mason's hand tool of the prior artcomprises a blade 10′ , a handle 20′ , and a head cap 25 30′ . Thehandle 20′ is made of a plastic material and is devoid of a skidproofsurface enabling the hand of a person to get a firm grip on the handle20′ . The head cap 25 30′ is fastened with the head end of the handle20′ by rivet or adhesive and is therefore vulnerable to being detachedfrom the head end of the handle 20′ especially at the time when the headcap 25 30′ is used by a mason to hit a nail or screw that is notcompletely fastened onto something.

SUMMARY OF THE INVENTION

The primary objective of the present invention is therefore to providean improved hand tool which is free from the drawbacks of the prior arthand tool described above.

In keeping with the principle of the present invention, the foregoingobjective of the present invention is attained by a hand tool comprisinga blade, a handle, and a head cap. The handle is provided with askidproof surface to enable the hand of a person to get a firm grip onthe handle. The handle and the head cap are made integrally of a rigidplastic material by injection molding.

The foregoing objective, features, functions, and advantages of thepresent invention will be more readily understood upon a thoughtfuldeliberation of the following detailed description of a preferredembodiment of the present invention with reference to the accompanyingdrawings.

DETAILED DESCRIPTION OF THE EMBODIMENT

As shown in FIG. 3, a hand tool embodied in the present invention iscomposed of a blade 10, a handle 20, and a head cap 30.

The handle 20 is fastened at one end thereof with the blade 10 which isused in spreading cement mortar or things of that nature. The cap 30 isfastened with the head end of the handle 20. In the preferred embodimentof the present invention, the handle 20 and the head cap 30 are madeintegrally of a rigid plastic material by injection molding. The handle20 is provided on the outer surface of the one end thereof with askidproof area 12 providing friction to enable the thumb and the indexfinger to hold the skidproof area 12 securely.

In order to enhance the fastening of the head cap 30 with the head endof the handle 20, the head cap 30 may be provided with a plurality ofprotrusions 31 each having a retaining head 32 which is greater indiameter than the protrusions 31, as shown in FIG. 5 and FIG. 7. Thehead cap 30 is thus securely attached to the handle 20, best shown inFIGS. 5 and 7. Now referring to FIG. 4, and FIG. 6, in anotherembodiment of the invention, the head cap 30 is provided with aplurality of threaded holes 35 and bolts 33 which are engaged with thethreaded holes 35. Each bolt 33 has a head 34 which provides a similarfunction the retaining head 32 of FIG. 5. The head cap 30 is thussecurely fastened with the handle 20, thanks to the protrusions 31 orthe bolts 33 which are securely anchored in the head end of the handle20. The head cap 30 of the present invention is not vulnerable to beingseparated from the head end of the handle 20 even if the head cap 30 isused to hit a nail or screw that is not completely fastened ontosomething.

The embodiment of the present invention described above is to beregarded in all respects as being merely illustrative and notrestrictive. Accordingly, the present invention may be embodied in otherspecific forms without deviating from the spirit thereof. The presentinvention is therefore to be limited only by the scope of the followingappended claims.
